Pinhole Surgical Technique (PST) is a breakthrough cosmetic treatment for gum recession invented by Dr. John Chao.

Dr. Andrew K. H. Lee has been trained by Dr. Chao to perform the minimally invasive procedure which is incision and suture free. The procedure involves a needle which is used to make a small hole in the patient’s existing gum tissue. Through this pinhole, special instruments are used to gently loosen the gum tissue. These tools help expand and slide the gumline to cover the exposed root structure.

I performed the Pinhole Surgical technique (PST) for a patient 3 days ago in the recession area from the upper left canine to the upper left molar. Pictures taken before the procedure and 3 days after are shown. Notice the improvement of the gum line where the recession was present from the “before” picture. Our patient took Tylenol for pain control, but other than some food restrictions and oral hygiene precautions, he was able to eat normally a few hours after the procedure. No scalpel or sutures (stitches) were used in this procedure! Our patient was very happy at the outcome and he gave us permission to use his pictures!
